Abstract

A battery module of the present invention is adaptable to be utilized in various configurations including and not limited to an overlapping battery cell packaging configuration and a vertical stack battery cell packaging configuration used in an automotive vehicle. The battery module has a plurality of battery heatsink assemblies with the cells disposed therebetween.

Claims

1. A battery assembly for a vehicle having a device for introducing fluid therein thereby affecting temperature of said battery assembly, said battery assembly comprising:

a plurality of prismatic cells having terminal ends;

a plurality of spacers extending between said prismatic cells with each spacer presenting terminal edges with at least one of said terminal edges of said spacers extending beyond said terminal ends of said prismatic cells, said spacers and said prismatic cells being removable interconnected with one another thereby applying pressure to said prismatic cells; and

a temperature affecting element supported by and continuously extending over said terminal edges oriented in a generally parallel relationship with said housing thereby selectively increasing and decreasing temperature of said prismatic cells.

2. A battery assembly as set forth in claim 1 wherein said temperature affecting element is further defined by a heater blanket continuously extending over said terminal edges.

3. A battery assembly as set forth in claim 2 wherein said heater blanket is further defined by a water jacket.

4. A battery assembly as set forth in claim 2 wherein said heater blanket is further defined by an electrical resistor for generating heat.

5. A battery assembly as set forth in claim 1 wherein each said spacer is further defined by a plate from at least one of heat insulating material and heat absorbing material with said plate defining said terminal edges formed as bends presenting an L-shaped configuration defining an angle of at least ninety degrees and aligned with one another to form at least one generally continuous surface with said temperature affecting element being supported by and continuously extending over said at least one generally continuous surface.

6. A battery assembly as set forth in claim 47 including a pair of terminal plates engaging said spacers with said prismatic cells disposed therebetween to form said battery assembly.

7. A battery assembly for a vehicle comprising;

a plurality of cells having terminal ends and tabs at each of said terminal ends,

a plurality of spacers extending between said cells with each spacer presenting terminal sides to mate with said tabs of each of said cells, said spacers and said cells being removable interconnected with one another thereby applying pressure to said cells; and

each of said tabs being at least partially covered by a plating material to reduce impedance as said cells are connected with one another.

8. A battery assembly as set forth in claim 7 wherein said plating material includes at least one material such as Sn, Ni, Au, Ag.

9. A battery assembly as set forth in claim 7 each of said tabs is entirely covered by said plating material to reduce impedance as said cells are connected with one another.

10. A battery assembly as set forth in claim 7 each of said cell is a prismatic cell.
